Metric Butt Splices

Metric Butt Splices are actually a fairly common and useful connector used in electrical work. Metric Butt Splices are a form of so called “crimp” connectors. Crimp connectors are used to terminate wires safely, or connect one wire to another. The wire is inserted into the connector. Then the connector is “crimped”, usually with pliers. As a result, the connector is bent and deformed around the wire. This crimping forces the wire into contact with the metal inside the connector. The other end can either be crimped to terminate the wire. Alternatively the process can be repeated on the other side, with another wire, to connect two wires. The metric butt splice connector is simply a cylindrical crimp connector with one crimp on each end.  Some butt splice connectors are manufactured with heat shrinking ends which contract around the wire when exposed to heat, leading to a better seal between the wire and butt splice connector.convenient, easy to use

Given its simple design and purpose, why should you use a metric butt splices ? Typically, crimp connectors and soldering are two common methods of connecting wires. For many applications, the butt splice connector holds considerable advantages over soldering. Butt splice connectors are cheap and easy to use. Soldering equipment takes much longer to set up and use. Butt splice connectors are also safer than soldering equipment, with no heat and no toxins. Overall, the butt splice connector is a great connector to have. It is safe, convenient, easy to use, and cheap.
